Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 344 AM EDT Wed Oct 24 2018 Valid 12Z Wed Oct 24 2018 - 12Z Fri Oct 26 2018 ...Rainfall to move from the southern Plains to the Southeast over the next few days... ...Snow will come to an end for northern New England... ...Active weather to occur for the Pacific Northwest... As an upper level trough exits the Four Corners and moves toward the Plains, showers and thunderstorms will continue across the Plains along with the lower Mississippi Valley today. The heaviest precipitation is expected along north and central Texas eastward into western Louisiana/Arkansas. Light to moderate rain will occur in the central Plains, including the High Plains in Colorado. At the surface, low pressure will begin to lift northward toward coastal Louisiana. This will finally shift the precipitation away from Texas and into the lower Mississippi Valley and portions of the Southeast by Thursday morning. This surface low will move from the Southeast toward the Tennessee Valley. Showers and thunderstorms will increase across regions from northern Florida to the Carolinas and the southern portions of the Ohio Valley on Friday--with precipitation moving farther north into the Mid-Atlantic by the start of the weekend. In terms of flash flooding, a marginal risk has been issued for southeast Texas to coastal Louisiana, shifting to the eastern Gulf Coast by Thursday. The surface low that has been bringing light to moderate rainfall to coastal New England along with snow in the interior will continue lifting northward into Canada during the day. As this low pressure moves farther away, precipitation will taper off--including the snow. However, northern Maine will receive snow today--with light amounts across southwest Maine into northern New Hampshire. Precipitation will end completely by early Thursday morning. Multiple systems will move across British Columbia and the Pacific Northwest through the short term period, bringing active weather with them. The first frontal system will approach these areas later this afternoon. Precipitation will increase significantly tonight and into early Thursday morning--with snow in the higher peaks in western British Columbia and very light amounts in the far northern portions of the Washington Cascades and the northern Rockies. Precipitation will continue across the Pacific Northwest in addition to the northern Rockies on Friday as another frontal system approaches. The trend for temperatures will remain the same as it has over the last few days with below average temperatures in the east and above normal for the west. Texas will remain significantly below average today--with highs only reaching to the low 60s as precipitation continues across the state. By Thursday, high temperatures will recover to near normal.
